PNEUMATIo-TIR ARMOR.

.To all whom it may concern:

Be it known that I, LEEWV. GALLOWAY, a citizen of the United States,residing at Norwood, in thecounty of San Miguel and State of Colorado,have invented `certain new and useful Improvements in Pneumatic# TireArmors; and I -do declare the following to be a full, clear, and exactdescription Aot the invention, such as will enable others skilled-in theait. to which it 'appertains to make and use the same. My invention hasrelation to pneumatic tire armors, and it consistsin Athe construe!tionand arrangement of parts, as' will be. hereinafter described andparticula rly pointedout in the claim.

In the accompanying drawings, Figure l is an-elevation of a. tire armorembodying the )neudetail lonsaine' on a. transverse gitudinal sectionalView of the larger scale; and Fig.' 3 is a detail sectional view' of thesame. y The shield l is made of suitable metal,` is annular in form toextend around the pneumatic tiren and is here'v shown as concavoconvexis cross section to adapt the same to fit snugly on the pneumatic tire.In practice, the interior diameter of the shield is somewhat less thanthe normal exterior diameter ofthe pneumatic tireso'that when fittingthe shield yon thetire, th'elatterbe- C Omes compressed and Atheexpansive 'action of the'tire serves 'tocause the shield to be firmlyretained thereon. It will be observed by reference to Fig. 3 that theedges 2 of the shield are spaced somewhat -from therim of .the wheel,that is'to say, the sides of the said shield extend onlypartially-'over'.the sides of the pneumatic tireA and hence a s aceisleft between the edges of thesaid shied and understood.4 On the treadportion or pe-f riphe'ry of -the shield is the tread ring-,3. w ich ishere shown. as fiat snugly around the shield 1.

The' said 'studs-arehere shown as vhavingscrew Shanks which in thetread ring bear on`.the periphery of the tread rings. Hence, saidstuds are removable andcan be renewed when they become'worn. vW'henthe treadring becomes worn,-it can b e removedv and vreplaced by vanother so that-the life .of theannular shield l may be indefinitelyv pro` longed.

From the `foregoing description, taken in connection with theaccompanying drawings, the' construction' and operation o Athe`invention willbe readily understood without requirin-g a more extendedexplanation.vv
